Patent EA-002901-B1 (EA)
Title: Radiant energy concentrator
IPC: F24S23/79
Filed: 1999-07-07
Abstract: 1. Radiant energy concentrator which comprises light beams receiving layer made in the form of a set of beams collecting members arranged on a same level, characterized in that some layers are provided under and parallel to said receiving layer, the layers being provided with reflectors, said collecting members of said receiving layer are grouped such that each group has a central member and located adjacently to one another peripheral members arranged about said central member, said reflectors in a layer provided under said receiving layer are arranged such that the beam coming out of the outlets of said peripheral collecting members above said layer are directed to the intermediate reflectors arranged cirrcumferencially around the centre of the group, said intermediate reflectors directing the received beams to the outlet which is coincident with the axis of said group centre, outlets in each layer are grouped in a similar manner as that of said receiving layer and peripheral reflectors of each following layer direct the beams coming out of the preceding layer's peripheral outlets to the respective intermediate reflectors which direct the received beams to the outlets coincident with the axis of the group centre, and the distance between a group centre and group periphery in each following layer exceed that in each preceding layer. 2. A concentrator according to the Claim 1, characterized in that said receiving layer is made in the form of a set of funnel-shaped members arranged in a hexagonal honeycomb manner and having beams reflecting working surfaces, and six peripheral reflectors from the group of reflectors arranged under the said receiving layer are connected with the intermediate reflectors arranged about the centre of the group by means of the canals having reflective surfaces and make six-pointed stars. 3. A concentrator according to the Claim 1, characterized in that said light beams receiving layer is made as combination of orthogonally arranged paraboloidal-hyperboloidal concentrators. 4. A concentrator according to the Claim 1, characterized in that said light beams receiving layer is made in the form of a set of orthogonally arranged collecting lenses. 5. A concentrator according to the Claim 1, characterized in that said light beams receiving layer is made in the form of orthogonally arranged light collecting funnel-shaped members, above said funnel-shaped members square-shaped collecting lenses are provided, the optical axis of each of said lenses matching that of said funnel-shaped members, and the peripheral reflectors being provided on the layers which are arranged under said light receiving layer are connected with respective intermediate reflectors by means of the canals having reflective surfaces, the canals jointly making eight-pointed stars and a lens is in coincidence with each central member outlet and each layer central outlet. 6. A concentrator according to the Claim 5, characterized in that lenses are in coincidence with outlets of light beams receiving layers peripheral members and with peripheral outlets of each layer. 7. A concentrator according to the Claims 4 to 6, characterized in that said lenses are the Fresnel lenses.
